Abstract: Storing messages intended for a communication terminal in a service circuit associated with the local network of a switch node serving the communication terminal. A switch node may have one or more local networks and can use a service circuit of these networks to store the message. If the switch node does not havecapacity to store the message, the switch node will request that another switch node store the message. When it is necessary to process and store a message for a communication terminal connected to a local network, the service circuit associated with the local network may be busy and unable to process the call or the servicecircuit may not have sufficient memory to store a message. In which case, the switch node will attempt to find a service circuit with the ability to process the message and store the message on another local network controlled by the switch node. If theswitch node cannot find a single service circuit that has both processing capability and storage capability, the switch node will attempt to find a service circuit on one local network that has processing ability and a service circuit on another localnetwork that has storage capacity. The message is then stored on a local switching network of the other switch node. If the switch node request another switch nodestore the message, the other switch node uses the same procedures described above for identifying a service circuit and storage capability.

Granted: 2002-11-05
Abstract: The invention is directed to a brush section  (1)  for an electric toothbrush which includes a mounting tube (2) in which a shaft  (7)  rotary about a longitudinal axis  (3)  is received. Further,  the brush section (1)  includes a bristle carrier (11) from which bristles (15) extend in the direction of a brush axis (14).   The bristle carrier  (11)  is rotary about a transverse axis  (19)  by means of a bearing pin  (21).   By means of in particular a  tapered disk  (24),  the brush axis  (14)  and the transverse axis (19) define between them an angle (28) departing from an apex (29).  In operation of the electric toothbrush, the bristle  carrier  (11)  performs  a  nutating  motion  about  the transverse   axis    (19).       This   effects   a   revolving approaching/receding motion of the  free ends  of  the bristles (15) resulting in an improved cleaning action on a user's teeth.

Title: Packet radio system and methods for a protocol-independent routing of a data packet in packet radio networks
Inventor: AHOPELTO JUHA-PEKKA
IPC: H04B7/26
Filed: 1996-01-08
Granted: 2008-08-05
Abstract: The present invention relates to a protocol-independent routing of data packets between a mobile station of a packet radio network and a party (Host) connected to an external network. In the invention, a data packet of an extraneous protocol (IPX) is transferred through a packet radio network using a second protocol (X.25) as encapsulated in a data packet according to the second protocol. The transferring packet radio network does not thus need to understand the protocol of the transferred extraneous data packet or to be able to interpret the contents of the data packet. A data packet network is connected to other packet radio networks, data networks or the backbone network between packet data networks via a gateway node (GPRS GSN), which uses the network-internal protocol (X.25) towards the dedicated packet network and the protocol of each network towards other networks. When a data packet is transferred via a gateway node from a network into another network, the data packet is encapsulated in a packet according to the protocol of the new network. When the encapsulated data packet arrives in a node which supports the protocol of the encapsulated data packet, the encapsulation is stripped away and the data packet is routed forward according to the protocol of the data packet.

Abstract: Information is entered and validated by the operator of a dialysis machine by converting (230) the entered information into a first form using a first conversion relationship such as ASCII. The information in the first form is next converted (238) into a second form using a second conversion relationship, such as floating point numeric. Thereafter the information in the second form is converted (244) back to the first form using the first conversion relationship. The information in the first form which resulted from the third conversion (244) is displayed (246 and 248) for acceptance or rejection by the operator. Displaying the information resulting from sequential multiple conversions (230, 238, and 244) assures an opportunity for the operator to evaluate the entries for accuracy. Re-display of the previously entered information repeatedly presents the operator with an opportunity to recognize human-induced errors.

Abstract: Methods and apparatus for hosting a network service on a cluster of servers, each including a primary and a secondary Internet Protocol (IP) address. A common cluster address is assigned as the secondary address to each of the servers in the cluster. The cluster address may be assigned in UNIX-based servers using an ifconfig alias option, and may be a ghost IP address that is not used as a primary address by any server in the cluster. Client requests directed to the cluster address are dispatched such that only one of the servers of the cluster responds to a given client request. The dispatching may use a routing-based technique, in which all client requests directed to the cluster address are routed to a dispatcher connected to the local network of the server cluster. The dispatcher then applies a hash function to the client IP address in order to select one of the servers to process the request. The dispatching may alternatively use a broadcast- based technique, in which a router broadcasts client requests having the cluster address to all of the servers of the cluster over a local network. The servers then each provide a filtering routine, which may involve comparing a server identifier with a hash value generated from a client address, in order to ensure that only one server responds to each request broadcast by the router.

Filed: 1998-04-01
Granted: 2001-05-29
Abstract: The present invention provides a feed-forward amplifier having a predistortion circuit to provide a sufficient compensation for a variation in temperature. When a predistortion circuit 3 is used to minimize distortion in a main amplifier 6, the circuit 3, a variable attenuator 4, a variable phase shifter 5, and a main amplifier 6 are located in this order and a control circuit 19 controls the variable attenuator 4 and variable phase shifter 5 so that a carrier component, that is, an input signal, in a detected distortion component decreases to a minimum. In this manner, when the gain of the main amplifier 6 varies due to a variation in temperature, the preceding variable attenuator 4 and variable phase shifter 5 compensate for the variation of the gain. The input level of the predistortion circuit 3, however, is not affected, so the relationship between output levels of the predistortion circuit 3 and main amplifier 6 remain unchanged compared to the amount prior to the temperature variation, thereby providing the same compensation effect.

Abstract: A multistage gaseous and liquid phase separation type condenser has a pair of headers disposed in parallel with each other, and a plurality of flat tubes each connected to the headers at opposite ends thereof and corrugated fins interposed between adjacent flat tubes. Each header is divided by baffles into four chambers. The second header has a receiver and chambers of the second header have communication passageways for placing the chambers of the second header in flow communication with the receiver. The first header has an inlet pipe connected to a middle chamber thereof so as to form an inlet path and an outlet pipe connected to a lower chamber thereof. While the refrigerant flows through the paths defined by a plurality offlat tubes, a first separation of gaseous and liquid phases of the refrigerant occurs within the second header so that the separated gaseous refrigerant is recondensed flowing through an upper path above the inlet path and introduced into the receiver via the communication passageway, whereas the separated liquid refrigerant is introduced into the receiver. A second separation of gaseous and liquid phases of the refrigerant occurs within the receiver in connection with a certain amount of the liquid refrigerant stored in the receiver. The liquid refrigerant in the receiver is communicated with the lower path via a lower communication passageway formed in the lower chamber of the second header.
